cp-demangle.c (demangle_name): Initialize template_p in local name case.

Browse Source 
* cp-demangle.c (demangle_name): Initialize template_p in local
	name case.  Don't re-add substitutions as candidates.
	(demangle_nested_name): Use <unqualified-name>.
	(demangle_prefix): Likewise.  Don't add template names as
	substitution candidates twice, or re-add a substitution or the
	last prefix component.
	(demangle_local_name): Adjust output format.
